I have a string containing HTML escape characters (for <
and >
) that I am trying to render inside a div
using innerHTML. the escaped characters are not supposed to be rendered like normal html, but rather as text. However, they still do, so is there a work around for this?
NOTE: the objective is to display a few (meaning not all) tags as normal text.
Here is an example implementation:
var string = "<div>yolo</div>";
string = string.replace(/</g, '<'); //replaces all '<' with its escape character
string = string.replace(/>/g, '>'); //replaces all '>' with its escape character
string = string.replace(/(=|%|\/|\*|-|,|;|\+|<|>)/g, "<span class=\"sc\">$1</span>");
//the last line adds special formatting
//to certain characters using CSS (not shown)
//and a span tag with class, "sc".
//this is the reason that I cannot just simply
//use innertext instead of innerhtml
document.body.innerHTML = string;
PS please give an answer in pure JavaScript. I do not care if you add a jQuery solution, I just need a pure javascript one.
It doesn't work properly because you're replacing the ;
s with <spans>
. Try replacing the whole <
first to prevent your span-replacer from breaking the entities.
eg
var string = "<div>yolo</div>"; string = string.replace(/</g, '<'); //replaces all '<' with its escape character string = string.replace(/>/g, '>'); //replaces all '>' with its escape character string = string.replace(/(<|>|=|%|\\/|\\*|-|,|;|\\+|<|>)/g, "<span class=\\"sc\\">$1</span>"); //the last line adds special formatting //to certain characters using CSS (not shown) //and a span tag with class, "sc". //this is the reason that I cannot just simply //use innertext instead of innerhtml document.body.innerHTML = string;
.sc { color: red; font-weight: bold; }
如果使用jQuery,则可能需要处理text()
而不是innerHTML()
。
